Folk practice reads the waxing half of the cycle (new moon to full moon) as the window for beginnings and growth, and the waning half as the window for review, release, and rest. The day links open that date's full moon read — phase, energy, and the day's other six traditions.
The phase table is computed from the moon's actual phase angle, but the meanings attached to each phase are symbolic traditions, not predictions. Observation safety, weather, and practical plans always come first.
